A large-scale power company spanning 1,741 locations and nearly 20,000 services was absorbing persistent AT&T billing errors and escalating POTS rates across a rural, geographically dispersed network with no structured process to catch them.
Industry: Energy & Utilities • Carrier focus: AT&T • Engagement: Initial 3-year results, with continued ongoing engagement.
About the client
A large-scale power company with hundreds of locations across rural service territory, requiring a diversified network of regional and national carriers to meet power customers' needs. The geographic footprint and carrier mix made it difficult to validate billing accuracy without a structured, contract-first audit.
Scope of engagement
- 19,558 total services reviewed
- 1,741 locations covered
- 3-year program timeframe
The challenge: persistent AT&T billing errors and rising POTS rates
The client engaged Valicom to address persistent telecom billing inaccuracies and escalating service costs across an AT&T-anchored environment spanning more than 1,700 locations and nearly 20,000 services reviewed. The primary issue was ongoing AT&T billing errors, where numerous circuits were invoiced at rates that did not align with contracted pricing. On top of those discrepancies, AT&T had begun increasing rates on hundreds of POTS lines, creating growing cost exposure on services that were still operationally required to support a rural, geographically dispersed customer base. Without a contract-first audit and active dispute management, those errors and rate hikes would have continued to compound month over month.
The Valicom solution: a contract-first, circuit-level audit
Valicom conducted a comprehensive audit of the AT&T environment and billing practices, working through 19,558 total services with a contract-first, circuit-level approach to re-engineer the cost base.
- Contract & Rate Validation. Obtained and reviewed all AT&T contracts, then established expected contracted rates at the individual circuit level and compared them against live billing to surface discrepancies across all 1,741 locations.
- Billing Dispute & Recovery Management. Identified multiple incorrectly billing circuits, submitted detailed disputes with corrected rates by circuit, and actively managed each through resolution, confirming accuracy on subsequent invoices.
- POTS Cost Optimization. Confirmed business need with the client, then recommended and implemented an AT&T CompleteLink contract to lock in reduced rates across hundreds of lines, including preparation, submission, and execution end-to-end.
- Delayed Implementation Recovery. When AT&T delayed rate implementation, Valicom filed additional disputes to recover the retroactive charges associated with the delay.
Why a circuit-level audit matters
Carrier billing rarely fails in obvious ways. Errors hide in mismatched rate codes, expired promotional pricing, and post-renewal drift. By rebuilding the contracted rate for every circuit and comparing it against live invoices, Valicom turned an opaque AT&T bill into a line-by-line recovery and savings plan.
Quantifiable business impact: recovery, savings, and stabilized billing
Across the three-year engagement, two parallel workstreams, circuit billing corrections and POTS optimization, delivered immediate one-time recovery and substantial recurring savings, with 50% of ongoing savings implemented in the first six months.
| Outcome | Impact | Detail |
|---|---|---|
| Circuit billing credits | $441,000 | One-time recovery from disputed AT&T circuits |
| Monthly circuit savings | $40,500 | Ongoing, after disputes corrected on future invoices |
| POTS line savings | $51,000 / mo | Locked in via AT&T CompleteLink agreement |
| Delayed-implementation credit | $130,000 | Retroactive recovery for AT&T implementation delay |
| Time to first 50% of savings | 6 Months | Half of ongoing savings implemented in first six months |
| Annualized run-rate savings | ~$1.10M | $91,500 monthly × 12 across circuits and POTS |
